Question

Wired Faculty App

Dust generally settles down in a closed room. Explain.

Solution

Dust particles being small spherical particles remain suspended in air during dusting.

Terminal velocity is given by v ∝ r^2.Since the dust particles are minutely small, these particles will acquire a small terminal velocity. Hence, the particles will settled down in a closed room after some time.
